I've got a few things running for my TechDays sessions next week. They are working fine on my home network. Now, I know that the conference will have WiFi, but in my experience this can be problematic. Sometimes they use browser based authentication steps which are hard to replicate on a device with no screen, keyboard or mouse.

But I have a plan. I've got a portable access point that I use on occasions just like this. I know exactly which shelf it is stored on, in a nice little case and everything. So I go and grab it. Of course it's not there. It's not anywhere. Blarst.

However, I do have a Raspberry Pi 3 which I was planning to take along as well. And it turns out that it will work as an access point too. And setting it up is a dead doddle. I started with the howto here. That got me the Windows 10 IoT Core Dashboard which is an awesome little program that will create an SD card to use to boot your Pi and then take you through connecting and configuring it. The great thing for me is that it lets you use a "naked" Pi, with no keyboard, mouse or screen. All the configuration can be done via the browser based control center.

If you want to turn your Pi into an access point just head for the IoT Onboarding page you can see above, select a suitably obscure SSID and password and then save them. (I'd advise against the defaults). After a reboot you should have an access point which clients can connect to.

If you want to share the wired network connection from your Pi you have to actually turn this on. The user interface here is a bit rubbish to be honest. There's nothing I could see that indicates if the sharing is on or off, and you have to make sure that you connect the right adaptors at each end. Which is why you might find the screenshot useful. Just select the items that you can see in the "Access point adaptor" and "Shared network adaptor" and then click the "start shared access" button. And then it all just works. Awesome.

One tiny gotcha. On my Pi the SSID gets a bunch of hex characters added to it. HullSSID would probably change to XY_HullSSID_ED50. Browse for the WiFi connection with another device before you put the text into a client program.
